THREADED PISTON DISASSEMBLING
PROTECT THE FINISH ON THE ROD AT ALL TIMES. DAMAGE TO
THE SURFACE OF THE ROD CAN CAUSE SEAL FAILURE.
Fix the rod into the vice.
NOTE: Before attempting to disassemble the piston remove
any accessible seals.
Figure 5-24.
NOTE: Apply heat to break the bond of the sealant between
the piston and the rod before the piston can be
removed.
WARM THE SURFACE INDICATED MAX 300°C
Avoid overheating, or the parts may become distorted or
damaged.
Figure 5-25.
Apply sufficient torque for removal while the parts are still
hot. The sealant often leaves a white, powdery residue on
threads and other parts, which must be removed by
brushing with a soft brass wire brush prior to reassembly.
